# Svelte Virtual List vs virtua

virtua is a zero-config multi-framework virtualizer. Svelte Virtual List is narrower and Svelte-specific.

## Overview

virtua ships virtual list and grid components for React, Vue, Solid, and Svelte. Its design emphasizes zero-config virtualization, dynamic size handling, reverse scrolling, and broad UI scenarios. @humanspeak/svelte-virtual-list focuses on a small Svelte 5 list API with vertical and horizontal layouts, Svelte snippets, SSR-friendly hydration without a manual item-count prop, and built-in feed loading.

## Svelte Virtual List strengths

- Svelte 5-native component API with snippets and TypeScript generics
- Dynamic height measurement without requiring a size map up front
- Built-in infinite loading hooks for feed and pagination workflows
- Imperative scroll method with index and alignment control
- Vertical and horizontal layouts, including reactive orientation switching
- SSR-friendly package for SvelteKit apps
- Zero runtime dependencies and MIT licensed
- Svelte-specific docs and examples instead of a shared multi-framework surface
- Integrated load-more threshold API

## virtua strengths

- Very broad virtualization feature set
- List and grid components
- Strong fit for reverse, RTL, mobile, sticky, and placeholder scenarios
- Multi-framework package for teams sharing patterns across stacks

## Svelte Virtual List limitations

- Focused on one-dimensional lists, not grids or masonry layouts
- Horizontal mode is LTR-only in the current release
- Requires Svelte 5
- Newer package with a smaller ecosystem than older virtualizer projects

## virtua limitations

- Broader API surface than many Svelte-only list views need
- Infinite loading remains a pattern you wire around the component
- Svelte usage shares mindshare with several other framework targets

## Verdict

Choose virtua for broad virtualization coverage, grids, reverse/RTL scrolling, and multi-framework consistency. Choose @humanspeak/svelte-virtual-list for a focused Svelte 5 vertical or LTR-horizontal list with dynamic measurement, responsive axis switching, SSR-friendly hydration without a manual item-count prop, scrolling methods, and load-more behavior.
